摘　　要：构建了一种光标签交换网络中可行的具有业务汇聚、分组重组、突发帧封装等功能的边缘节点结构,提出了一种适合于在突发环境下传输的帧格式。在此基础上搭建了光标签交换演示平台,该平台承载的光载荷速率为2.5 Gbps,支持4路千兆以太网业务的接入,并成功进行了流媒体传输实验。A feasible optical label switching（OLS） edge node with the function of traffic aggregation, packet reorganization and burst-frame encapsulation was realized. And a specific burst-mode frame format suitable for OLS networks was proposed. Then, an OLS network platform with the optical payload rate up to 2. 5 Gbps was constructed based on three edge touters, each with 4 gigabit Ethernet access channels. The video streaming over this network was also successfully transported.
